How to use

  1. 1.Optionally adjust the focus, short-break, and long-break lengths (default 25 / 5 / 15 minutes), then press Start to begin your first 25-minute focus session.
  2. 2.Work on a single task until the countdown reaches zero — the timer automatically switches to a break, and back to focus, keeping the cycle going for you.
  3. 3.Use Pause and Resume when you need to step away, Skip to jump to the next phase, and watch the session counter track every focus block you complete.

About Pomodoro Timer

The Pomodoro Timer is a free, in-browser focus timer built around the Pomodoro Technique, a time-management method created by Francesco Cirillo in the late 1980s. The idea is deliberately simple: you break your work into fixed intervals called "pomodoros" — traditionally 25 minutes of uninterrupted focus — each followed by a short 5-minute break. After you finish four focus sessions in a row, you reward yourself with a longer 15-minute break before starting the next round. This timer runs that entire cycle for you automatically, so you can keep your attention on the task instead of the clock.

When you press Start, a large minutes-and-seconds countdown begins for the current phase. The moment a focus session reaches zero, the timer moves straight into a break; when the break ends, it rolls back into the next focus session. It tracks how many focus sessions you have completed and automatically swaps in the longer break after every fourth one, exactly as the method prescribes. You can pause and resume at any time, skip to the next phase when you finish early, or reset back to the very first focus session. If you prefer different intervals, the focus, short-break, and long-break lengths are all adjustable before you begin.

Why does working in 25-minute blocks help? A short, defined interval lowers the mental cost of getting started, because committing to "just 25 minutes" feels far easier than facing an open-ended task. The ticking countdown creates a gentle sense of urgency that discourages multitasking and makes it easier to say no to distractions until the break arrives. The scheduled breaks matter just as much as the focus blocks: stepping away to stretch, rest your eyes, or grab water prevents the slow drain of mental fatigue and helps you return sharper for the next session. Over a full day, the rhythm of focus and rest turns a vague to-do list into a countable series of finished pomodoros, which makes your progress visible and your planning more realistic.

The technique pairs well with a few simple habits. Before a session, decide on the single task you will work on so the 25 minutes have a clear target. If a stray thought or a new task pops up mid-session, jot it down and keep going rather than switching context. Treat each completed pomodoro as one unit of work when you estimate how long future tasks will take — after a week you will have a surprisingly accurate feel for your own pace.

Everything here happens entirely on your device. There is no account to create, no software to install, and nothing you do is uploaded to a server: the countdown, the phase switching, and the session counter all run locally in your browser using standard timers. That makes the tool fast to open, private by default, and usable whether you are studying, writing, coding, or working through chores. Bookmark it and start your first focus session whenever you need a clean, distraction-free way to get things done.

Frequently asked questions

What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method developed by Francesco Cirillo that breaks work into focused intervals separated by short breaks. You work for 25 minutes, rest for 5, and take a longer 15-minute break after every four focus sessions. The repeating rhythm keeps your attention fresh and turns a big task into a countable series of finished sessions.
Why is a focus session 25 minutes long?
Twenty-five minutes is short enough that starting feels easy and long enough to make real progress before your concentration dips. It is the original interval Cirillo used, and it strikes a practical balance between deep focus and regular rest. If it does not suit your work, you can change the focus length in the settings before you start — many people also try 50-minute blocks with 10-minute breaks.
Do my timer settings and sessions get saved or uploaded?
No. The timer, phase switching, and session counter all run locally in your browser, and nothing is sent to a server or stored in an account. Because everything stays on your device, the tool opens instantly and keeps your activity private. Note that reloading or closing the tab will reset the current timer and session count.
